1/ 0 all whom it may concern:

Be it known that I, MonTiMonn S. REY- noLns, a citizen of the United States, residing at Yates Center, in the county of l Voodson and State of Kansas, have invented a new and useful Medicine-Injecting Apparatus, of which the following is a specification.

This invention relates to apparatus especially designed for administering medicinal or other liquids, intravenously or otherwise, one of the objects being to provide apparatus in which an antiseptic solution is employed for the purpose of purifying the air which is used under pressure for forcing the medicinal liquid into the veins or body, it being possible to thoroughly sterilize the antiseptic solution and the medicinal liquid prior to using the same and while they are within the apparatus.

A further object is to provide apparatus of this character which holds the antiseptic solution and the medicinalliquid practically sealed so that it cannot become contaminated by the surroundingatmosphere subsequent to being sterilized and prior to being used, it being possible by means of the apparatus to prepare the mixtures or medicines in a laboratory and to carry them to the bedside of a patient without danger of contamination.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a central vertical section through the apparatus, said section being taken on the line AB Fig. 3.

Fig. 2 is an elevation of the apparatus, a portion thereof being broken away.

Fig. 3 is a plan. view.

Fig. 1 is a section on line CD Fig. 1.

Referring to the figures by characters of reference 1. designates an outer container providedwith a removable cap 2 which may have a packing 3 of any suitable material therein to seal the receptacle when the cap.

is in closed position. Concentricallymounted upon the bottom or inner face of the cap is a threaded circular flange a forming socket adapted to be detachably engaged by theupper end of an inner container 5 which is thus suspended within the outer container. Communication may be established between the containers in any suitable manner as by an inverted U-shaped tube 6 having its arms extended throughthe cap 2, one arm opening into the upper portion of the inner container 5, while the other arm opens into the upper portion of the outer container 1. txtending through the cap 2 and downwardly to a point close to the bottom of the container 5 is an outlet tube 7 having a crook S at its upper end from which extends a tubular arm 9 to which a flexible tube 10 maybe connected, this tube being extendedto the instrument used upon the body of the patient. Another tube 11 is extended downwardly through the cap 2 and into the container 1, terminating at a point adjacent the bottom of said container, the outer end of this tube 11 being adapted to be connected by a flexible tube 12 or in any other suitable manner to a suitable source of air under pressure. A. vent nozzle 13 is arranged on the cap 2 and communicates with the interior of the container 1, this nozzle having a valve 14.

In using the apparatus, the cap 2 is disconnected from the two containers 1 and 5 and a desired amount of antiseptic solution is placed in the container 1 while the medicinal liquid is placed in the container 5. Said container 5 is then placed in engagement with the wall or flange 4: of the central. socket in the cap after which the cap 2 is fastened onto the outer container 1. Nozzle 13 is opened and. the entire apparatus placed in boiling water so that the apparatus and its contents will be thoroughly sterilized. Any steam generated will be free to escape through the nozzle 18. Valve 1a is then closed and the apparatus is ready for use. When air under pressure is directed to the tube 11 it will flow downwardly therein and escape adjacent the bottom of the container 1. It will pass upwardly through the antiseptic solution in said container which will thus purify the air, after which said air will rise above the solution and How through the tube 6 into the top of the container 5. It will here press downwardly on the medicinal liquid in the container 5 and cause a portion of said liquid to be displaced outwardly through the tube 7. As shown in Fig. 2 both of the containers'should be graduated.

What is claimed is Apparatus of the class described, including an outer transparent graduated container, a closure removably mounted thereon, said closure having a central socket portion depending therefrom, an inner transparent graduated receptacle detachably engaging the walls of the socket portion and suspended therefrom concentrically within the outer container, said closure constituting means for sealing both containers, a pipe connection between the upper portions of the two containers, a valved steam vent carried by the closure and in communication with the interior ofthe outer container, an outlet tube extending through the closure from a point adjacent the bottom of the inner container, and an air inlet tube extending through the closure and opening into the outer container adjacent the bottom thereof.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
